Structures of bulk amorphous Zr41Til4Nil0Cul2.5Be22.5 alloy in amorphous, crystalline, supercooled liquid and liquid states

The amorphous and crystal structures of Zr41Til4Nil0Cul2.5 Be22.5 alloy have been analyzed with X-ray difractometer. The structures of bulk amorphous Zr41Til4 Nil0Cul2.5B22.5 alloy in solid, supercooled liquid and liquid states are almost of the same structure. The RDFs (Radius Distribution Function), the first coordination number, the first coordination radius, the correlation radius and atom number of the cluster were calculated for bulk amorphous Zr41Til4Nil0Cul2.5B22.5 alloy in different states. The first coordination sphere radii and the first coordination numbers are 0.312nm, 11.2 in solid state, 0.301 nm, 10.932 in supercooled liquid region and 0.305nm, 11.296 in liquid state.The crystal structure of Zr41Til4Nil0Cu12.5B22.5 alloy is consisted of several intermetallic compounds which are CuZr2,Be2Zr, etc. The reason of formation glass for this alloy is that there is a larger resistance for atoms to rearrange and form intermetallic comnounds in a long range order.
